The 2020 Chevrolet Trucks Silverado 1500 sits in the modern full-size pickup market where trim level, wheel package, and intended use can change the tire decision quickly. From work-oriented configurations to more appearance-driven and off-road-leaning sub-models, this generation Silverado asks owners to start with exact fitment before comparing tread style or load capability. Tire fitment spans six primary radial sizes, from 17-inch applications up to 22-inch wheels. Available product coverage here leans toward all-terrain BFGoodrich KO2 options in certain 17-inch and 18-inch sizes with raised white letter sidewalls. For a Silverado used on the road, on job sites, or for mixed-duty driving, matching the truck's exact sub-model and wheel setup is the first step.
Which Tire Size Is Right for The 2020 Chevrolet Trucks Silverado 1500
The 2020 Chevrolet Trucks Silverado 1500 uses six primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. These are all metric radial sizes, but they span 17-inch, 18-inch, 20-inch, and 22-inch rims, so confirming the truck's actual wheel setup comes first. Once that is settled, the decision shifts to selecting the right load specification, sidewall style, and tire type for how the truck is used.
275/50R22 is a metric radial size with a 275-millimeter section width, a 50-series profile, and a 22-inch rim diameter. On the 2020 Chevrolet Trucks Silverado 1500, it serves configurations that use a larger wheel package and a lower-profile truck tire than the 17-inch and 18-inch fitments. That sizing approach usually makes wheel confirmation especially important because a 22-inch application cannot be substituted casually with smaller-rim sizes. This is the size to evaluate when the truck already wears 22-inch wheels and the goal is to preserve the intended wheel-and-tire proportion.
Fit(s): Custom, Custom Trail Boss, High Country, LT, LT Trail Boss, LTZ, and RST
Construction: Radial|Rim: 20 in
275/60R20 is a metric radial size that combines a 275-millimeter section width with a 60-series profile on a 20-inch rim. For the 2020 Chevrolet Trucks Silverado 1500, it is one of the more widely used fitments across several sub-models, making it a common choice on trucks equipped with factory-style 20-inch wheels. Its sizing places it between the lower-profile 22-inch setup and the more traditional 17-inch and 18-inch applications. This size deserves close attention when matching an existing 20-inch wheel package and maintaining the truck's intended stance and clearance.
275/65R18 is a metric radial size with a 275-millimeter section width, a 65-series aspect ratio, and an 18-inch rim diameter. On the 2020 Chevrolet Trucks Silverado 1500, it appears on sub-models that lean toward a taller sidewall and a more substantial tire presence than the larger-wheel fitments. In available products, this size includes a BFGoodrich All-Terrain T/A KO2 option with raised white letter sidewalls, which gives it a distinctly truck-oriented appearance. It is the size to review when the Silverado uses 18-inch wheels and the priority includes all-terrain character as well as correct basic fitment.
255/70R17 is a metric radial size that uses a 255-millimeter section width, a 70-series profile, and a 17-inch rim. Within the 2020 Chevrolet Trucks Silverado 1500 range, it represents one of the narrower 17-inch fitments and should be matched carefully to the sub-model and wheel setup already on the truck. Its sizing differs meaningfully from the 265/70R17 alternative, so a buyer should not choose between the two by rim diameter alone. This size is the right starting point when the Silverado's configuration calls for a 17-inch tire with a slightly narrower section width.
265/65R18 is a metric radial size with a 265-millimeter section width, a 65-series profile, and an 18-inch rim diameter. For the 2020 Chevrolet Trucks Silverado 1500, it serves select 18-inch applications that differ from the wider 275/65R18 setup, so the exact wheel-and-trim combination matters. Even though both use 18-inch rims, they are not the same fitment and should be compared with attention to wheel width and overall vehicle setup. This size is the one to evaluate when the truck carries an 18-inch package but does not use the broader 275-width tire.
265/70R17 is a metric radial size with a 265-millimeter section width, a 70-series profile, and a 17-inch rim diameter. On the 2020 Chevrolet Trucks Silverado 1500, it is used on certain 17-inch applications and differs from 255/70R17 through its wider section width rather than wheel size. Available products include BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls and more than one load specification, which makes product comparison especially relevant in this size. It is a strong fitment checkpoint for owners who want to match an existing 17-inch setup while comparing all-terrain tire specifications more closely.
2020 Chevrolet Trucks Silverado 1500 Sub-Model Tires
Sub-model fitment on the 2020 Chevrolet Trucks Silverado 1500 varies widely, and several trims use more than one primary tire size. Checking the exact sub-model and actual wheel diameter is essential before comparing tires, especially because 17-inch, 18-inch, 20-inch, and 22-inch applications all appear across the lineup.

Silverado 1500 tire questions usually come down to exact size by sub-model, wheel diameter, and how to compare available all-terrain radial options. The FAQs below focus on fitment, product selection, and the maintenance checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2020 Chevrolet Trucks Silverado 1500?
The 2020 Chevrolet Trucks Silverado 1500 uses six primary tire sizes: 275/50R22, 275/60R20, 275/65R18, 255/70R17, 265/65R18, and 265/70R17. All of them are radial sizes, and the correct one depends on the truck's exact sub-model and wheel package.
The practical first step is checking the installed wheel diameter, because Silverado 1500 fitments here span 17-inch, 18-inch, 20-inch, and 22-inch rims. From there, confirm the exact sub-model and compare the current tire size on the truck so the replacement matches the wheel, overall setup, and intended use.
What size rim does a 2020 Chevrolet Trucks Silverado 1500 use?
A 2020 Chevrolet Trucks Silverado 1500 can use 17-inch, 18-inch, 20-inch, or 22-inch rims, depending on sub-model and wheel package. Rim diameter tracks directly with the tire size, so each tire fitment belongs to one specific wheel diameter rather than the whole Silverado lineup.
That matters because tires with different rim diameters cannot be substituted casually, even when the widths look similar. The safest approach is to read the wheel itself or confirm the tire size already installed, then compare replacement tires only within the correct rim diameter and compatible wheel-width range.
Why does the 2020 Chevrolet Trucks Silverado 1500 have more than one tire size?
The 2020 Chevrolet Trucks Silverado 1500 has more than one tire size because different sub-models and wheel packages use different fitments. Some trims offer multiple factory-style wheel diameters, while others use different widths or sidewall profiles even when the rim diameter is the same.
That means tire selection starts with the exact truck configuration, not the Silverado name alone. An LT, WT, Trail Boss, or High Country can call for different sizes, so checking the sub-model and actual wheel setup helps avoid choosing a tire that matches the model year but not the truck in front of you.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Chevrolet Trucks Silverado 1500?
Start with the correct primary size for the truck's sub-model and wheel diameter, since the 2020 Chevrolet Trucks Silverado 1500 uses six different radial fitments. After size is confirmed, compare construction, load specification, rim-width compatibility, and whether the tire's purpose matches how the truck is actually driven.
A road-focused truck and a mixed-use truck may need different priorities even within the same size. It helps to look at the current wheel setup, the load the truck carries, and whether appearance matters, then compare available tires in the correct size instead of trying to choose across unrelated Silverado fitments.
What sidewall styles are available for 2020 Chevrolet Trucks Silverado 1500 tires?
Available products shown for the 2020 Chevrolet Trucks Silverado 1500 use RWL sidewalls, meaning raised white letters. That sidewall style appears on the BFGoodrich All-Terrain T/A KO2 options available here for 275/65R18 and 265/70R17 applications.
Sidewall treatment changes the truck's visual character as much as the tread pattern does, especially on a late-model pickup with exposed wheel-and-tire presence. If the goal is to preserve a clean stock-style look or move toward a more assertive all-terrain appearance, the sidewall presentation is worth considering after size and wheel compatibility are settled.
What tire series are available for the 2020 Chevrolet Trucks Silverado 1500?
The tire series available here for the 2020 Chevrolet Trucks Silverado 1500 is the BFGoodrich All-Terrain T/A KO2. It appears in the 275/65R18 and 265/70R17 sizes and is offered as a radial truck tire with raised white letter sidewalls.
Series matters because it helps define the tire's intended character within the correct size. Once the Silverado's exact fitment is confirmed, comparing KO2 options by size-specific load specification, rim-width range, and overall intended use gives a better result than choosing by brand name or appearance alone.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Chevrolet Trucks Silverado 1500 restoration or clean stock-style build?
Yes, correct tire fitment still matters on a 2020 Chevrolet Trucks Silverado 1500, even though it is a newer truck than a traditional collector vehicle. The Silverado uses several distinct radial sizes tied to different wheel packages, so preserving the right size helps maintain the truck's intended stance, wheel proportion, and overall presentation.
A clean stock-style build benefits from matching the tire to the wheel diameter and trim-specific setup rather than choosing only by appearance. Before replacing tires for cosmetic reasons, confirm the existing wheel package and compare the current size so the finished look remains coherent and the truck keeps appropriate clearance.
Which sidewall style suits a clean-looking 2020 Chevrolet Trucks Silverado 1500?
The available sidewall style shown here is RWL, or raised white letter, on BFGoodrich All-Terrain T/A KO2 tires. That treatment gives a 2020 Chevrolet Trucks Silverado 1500 a more pronounced truck and all-terrain look than a plain blackwall presentation would.
Choosing the right appearance depends on the truck's personality and how visible the tire sidewall will be with its wheel package. On an 17-inch or 18-inch setup, raised white letters can become a strong styling element, so it helps to decide whether the goal is understated road use or a more deliberate all-terrain visual statement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Chevrolet Trucks Silverado 1500?
Yes, modifications can affect tire fitment on a 2020 Chevrolet Trucks Silverado 1500. Aftermarket wheels, changes in wheel width or offset, suspension lifts, leveling kits, lowering changes, or body alterations can all change how a tire clears the fender, suspension, and steering components.
Even when the replacement tire matches one of the Silverado's primary sizes, a modified truck may not behave like a stock one. It is smart to confirm the actual wheel dimensions, inspect turning and compression clearance, and compare the current setup before selecting a new tire for regular road use.
What should I inspect before driving a 2020 Chevrolet Trucks Silverado 1500 on new tires?
Before driving a 2020 Chevrolet Trucks Silverado 1500 on new tires, inspect the wheel diameter and width, confirm the tire size matches the truck's configuration, and check inflation pressure against the tire and vehicle requirements. It also helps to look for any obvious interference at the suspension, steering, and fender edges.
A short initial check can prevent problems that show up only after the truck is moving. Watch for rubbing at full steering lock, listen for contact over bumps, and recheck pressure after the first drives so the new tires settle in without avoidable clearance or setup issues.
What should I check before a longer drive in a 2020 Chevrolet Trucks Silverado 1500?
Before a longer drive, check tire pressure, tread condition, visible sidewall damage, and any sign of air loss on the 2020 Chevrolet Trucks Silverado 1500. On trucks using available KO2 fitments, it also makes sense to confirm that the tire's load specification suits the way the truck will be used on that trip.
A longer run puts more emphasis on stability and consistent inflation than short local driving. It is worth giving the wheels a quick visual inspection, making sure nothing is rubbing, and confirming that all four tires match the intended setup so the Silverado starts the trip with a sound baseline.
